Stereolithography (SLA)

If you need prototypes, patterns or end-use parts with the greatest accuracy, highest definition and best surface finish, SLA® models are an excellent investment and can optimize time and money at every stage of the production cycle.


The Technology

Stereolithography or SLA® Systems convert liquid plastic materials (photosensitive epoxy polymers) and composites into solid cross-sections, layer by layer, to build highly accurate three-dimensional parts of different geometries at the same time.

Step by step:

  • SLA® translates a CAD file into a surface model made up of thousands of small triangles.
  • File is sliced into many layers like a stack of cards and transferred into an SLA® System.
  • A laser in motion cures the liquid material in very thin layers, including interior and exterior layers, to a solid part.



SLA® parts are ideally used as master patterns for injection molding core and cavity inserts, thermoforming, sand casting, blow molding, and various metal casting processes.

  • Best accuracy and smooth surface finish
  • Extreme fine detail capability, ideal for micro parts
  • Wide range of material offering
  • Materials with PC (transparent) characteristics or high heat resistance
  • Thin walled parts (no less than 0.5mm)
  • 3 to 5 days turnaround



The most demanding industry applications benefit from SLA® as parts provide precision and can withstand high temperatures. Formula 1 and other Motorsports, for example, have been using SLA® technology for years to advance product performance and get ahead the competition with intense Windtunnel testing.

Other industries that are widely using the SLA® technology are:
Automotive, Motorsports, Windtunnel testing, Aerospace, Consumer products, Packaging, Electronics, Architecture, Medical, Entertainment & Animation and Government Research.

Finishing Options

Our attention to detail and superior finishing is unsurpassed. We provide four levels of finishing:

  • Concept -Support removed and sanded with a light bead blast all over. Ideal for concept validation.
  • Premium - All surfaces (exterior + interior) are finished to a high quality. Recommended for projects that are visual and require critical fitment to meet tolerances of +/-0.1mm to 0.2mm per 100mm.
  • Engineering - All exterior surfaces are finished to a high quality. Recommended for projects that require critical fitment to meet tolerances of +/-0.1mm to 0.2mm per 100mm.
  • Custom - High level of polishing for clear components
